I know what "bukkake" means, and I know what "die" means, but I'm not sure how they go together, nor do I understand how the rider keeps finding himself in situations in which he must choose between the two.

Here on Boing Boing, you'll see that terms like "bukkake" and "anal" rank disproportionately high in our stat logs, relative to the number of times we actually use them in our posts (bats eyelashes innocently).
